I was looking for a book, text, post or something talking about iPhone optimization but I couldn't find anything except for Apple documentation. I think it would be great to talk about which are the common steps you do when optimizing your apps performance. I'm now trying to improve my app memory usage and I've figured out it is really ...
I am using a method GA_googleFillSlot from google ad service to load the ads. Which has to be loaded on the right rail of the page in my web site. As part of speeding up my web site, I want to move the method with related javascripts to the bottom of the page. The javascript method creates a new div with id google_ads_div_<name of ad sl...
Hi I am making a page which calls a web service to fill a gridview this is returning alot of data, and is horribly slow. i ran the svcutil.exe on the wsdl page and it generated me the class and config so i have a load of strongly typed objects coming back from each request to the many service functions. i am then using LINQ to loop ar...
I have an ASP .NET web application which on the backend is talking to an ASMX web service. We have counted and the average wait time for the initial request is 20s. I am wondering if there is a way I can send the web service up to the server precompiled, thus negating the need for compilation. We have also noticed that IIS tends to recy...
I've seen some similar posts, but nothing quite like this... I have a website (Sharepoint). When I access a particular page that has many custom-coded webparts on it, the page takes ~30 seconds to load. I've used Firebug and confirmed that the long load time is the server working (in the "Net" tab the webpage timeline shows ~30 seconds ...
I have a Webforms, AJAX-enabled web page which, when rendering large amounts of data, is extremely slow to load in IE (we're married to IE - no other browser options). In an attempt to determine the source of the slowness, I viewed the HTML source (about 2.5 MB) and copied all of it (except for the Ajax JavaScript calls) to a blank .htm...
I have a JSF application where the UI components render very slowly in IE7 but give a much better performance.Dont know what can be done ,but just throwing this question out for suggestion if any setting/configuration makes it perform better ...
I have developed a little application that can play video from a rstp streaming sever (darwin in this case, but this is not relevant) by means of the VideoView widget (I have tried Mplayer+SurfaceView approach too). I use Wifi connection for this. The video plays just smooth when video is the only task. The small application should carr...
I have made a test project that makes HTTP POST requests in silverlight (using the HttpWebRequest and WebClient classes). I consistently get a performance of approximately 20 calls/s, which I think is very slow. The only data I send and receive are small strings (some 20 characters). What surprised me was that WCF (SOAP over HTTP) showed...
Which one of the C# <Key, Value> structure implementations has better performance and higher speed? P.S.1: I Have two thread, one of them writes into collection, and another one reads and writes into it. P.S.2: Key items are random numbers, and then my access is random. Write and read actions are simultaneous. I am using hashtable, but...
There are two tables that I join them together, one of them is a temp table and I create an index after creating the table. But it is said in the query execution plan above. what should I consider to convert all scan operations to seek operations? There are parts which are joins and where conditions... Regards bk ...
Hi, I have a doubt regarding the use of Berkeley Sockets under Ubuntu. In terms of performance and reliability which option is best? To send a high amount of messages but with short length or to send a low amount of messages but this ones with a large size? I do not know which is the main design rule I should follow here. Thank you all...
We are planning to implement ACL on our Linux platform. Only one particular group is going to come under ACL. This group would have at the max 20 users. All of the restrictions would be at directory level (not at file name level) Would this show any impact on the server's performance/responsiveness? ...
We're considering using UUID values as primary keys for our MySQL database. The data being inserted is generated from dozens, hundreds, or even thousands of remote computers and being inserted at a rate of 100-40,000 inserts per second, and we'll never do any updates. The database itself will typically get to around 50M records before w...
I am creating a site that allows users to share specific pages to the public. It is similar to how jsbin.com let's you create a public url of the script you're working on. The basic MySQL table I am working with now is: CREATE TABLE IF NOT EXISTS `lists` ( `id` int(10) NOT NULL AUTO_INCREMENT, `hash` varchar(6) NOT NULL, `created_...
Performance of INSERT and UPDATE statements in our database seems to be degrading and causing poor performance in our web app. Tables are InnoDB and the application uses transactions. Are there any easy tweaks that I can make to speed things up? I think we might be seeing some locking issues, how can I find out? ...
I'm trying to create an XML sitemap using CakePHP, from a table which has more than 50,000 records at the moment, each record equivalent to a URI in the sitemap. Now the problem I'm facing is CakePHP is running me out of memory while generating it, for two reasons: A find('all') is building a huge associative array of the entire set of...
I've tried to measure it with a small benchmark collection and my own tests, but the results stay the same or even get worse. I also couldn't find any benchmark data on the web to this question, so here it is: Is there really a performance improvement if I install native images of .NET assemblies? And if yes, in which areas and is it re...
Developers are sometimes scathing of mult-tier Enterprise web applications... 'Enterprise' is viewed by some as synonymous with slow, bloated and resource-hungry. Do frameworks such as Hibernate actually bring in a non-trivial impact on performance compared to writing your own DAOs or other less abstracted approaches? By non-trivial I s...
Has anyone ever tested, or does anyone know, the performance differences of these two different ways of rendering the same html content (other than the fact that one has imported the jquery library and the other hasn't, and that there are two requests in the Ajax version versus one)? Add HTML via Ajax <html> <head> <script src="jav...
